Poncho relative (6)
I believe the answer is:
serape
'poncho relative' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for serape that I've seen before include "Mexican male garment with hole for head" , "Blanket-like shawl worn by Mexican men" , "wrapper" , "Coloured wool blanket worn by Spanish American men" , "Mexican riding blanket for Pearse" .)
